Application filed October 26, 1905. Serial No. 284%.512

in the county of Johnsonand State of Arkansas, have invented certain new and useful Improvements in Cotton-Gin-Breast Hinges, oiY which 'the followingT is a specification.

This invention relates to certain improve ments in that class of cotton-gins in which circular or other saws pass between ribs on'the gin-breast and in their operation pull the lint downward and between the ribs, thereby freeing` it 'frein the seed. in this class of cotton-gine the ribs are carried by .a breast which has a hinged connection, so that the ribs may play freely, and heretofore great diliculty has been experienced owing to the fact that the saws wear away openings at the points the saweteeth engage with the cotton and pull the 'lint downwardly between the ribs, this opening becoming so large in time4 that the seed andother extraneous and. injurious matter may nass through theopening between the ribs with the lint,thereby darnaging the cotton and detracting from its niarlretable value.

The object or" my invention is to provide in acotton-gin of this character an improved hinged breast for the ribs, which breast will.

be so connected to the gin proper as to allow of its ready vertical adjustment, so that when the ribs are worn away, as betere de` scribed, the gin-breast may be moved vertically to compensate for the'opening that has been worn away, while at the saine time the breast is allowed to swing freely.

The invention consists, essentially, in an impro-ved construction of hine'e for the breast,

said hinge comprising pivotallyconnected members, one of which is provided with threaded lugs designed to accommodate the adjnstii1g-screw supported upon a plate attached to the 'stationary part of the giniraineworlr, so that by turning said screw the gin-breast may be lowered or raised, as may "be desired under the existing conditions.

For a full description of the' invention and the 'merits thereof and also to acquire a knowledge ofthe details of construction el the ineens for effecting the result reference is he had to the iollowii'ig description and acconipanyhig drawings, in which- Figure l is a iront view of the improved gin-breast embodying. my invention. Fig. 2 is a transverse sectional view thereoll sah` enlarged scale. Fig. 3ds a detail perspective view of the yspecific form 'of hinge employed and the locl/r'ingrap therefor. ,i

Corresponding and like parts 'are referred to in the following description and indicated in all the 'views of the drawings by the same reference characters.

Referring to the drawings, the numeral l designates the stationary portion ofthe ginto he hinged, said breast carrying' the ribs 3, between which the saws 4 pass. To the part l is rigidly attached. a plat-e 5 by screws or the like, and said plate is provided with an upper and a lower lug or ear each of which is provided with an opening or bore devoid of threads. To the inner side of the gin-breast 2 there is secured one lea.r` or member 7 et e. hinge 8, the other member or leaf of said hinge (designated 9) being provided with interiorly-tlueaded lugs er ears 10, as shown.

1i designates an adjusting-screw which mounted in the lowerrnost lug or ear and f iroviding a shoulder 13 on the screw, which journal for the lower end of the screw, and the upper end ot said adjustnig-screw il has bearing, in the uppermost lugr or ear 6 and is bear upon the under face of said lug. lThe adjusting-screw, as will be noted,engages with its threads the interiorly-tineaded lugs of the hinge member 9. V screw in one direction or the other it is nianifest that the entire' hinge 8 will beraised or lowered, as may he desired, and thereby result in the consequent raising orv lowering et' the gin-breast to adjust the ribs 3.

Each of the lugs before described is provided with angular sides fitting between the late 5 and the opposite plate or hingezneni ,er 9 to provide bearings or guide-surfaces which will prevent the attachn'ient from have in this instance provided a cap l5, which fits down aroiind the square or onal head of the screw and is provide with te extend over 'sonic stationary part, such as the framework 1, thereby preventing, as will be readily understood, the adjusting-screw from being; turned so lon as this cap remains stentiahy on. ne line a; w of l on an l in the described position.

framework to which the breast l? is designedy bears' upon said lug, thereby constituting a` Hence by turning said wabbling or showing in its movement, and ,y thereby holding the ribs hrinly to their work. To loch the adjusting-screw trein turning, I

polyge, downwardly-extending flange 16, designed is provided with a step 12 at its lower end,

provided also with a shoulder le, designed to IOO From the foregoing description in connection with the accompanying drawings it is scribed the combinationv with a stationary support, of a gin-breast, and a vertically-adjustable hinged connection /betvveen 'said breast, and the support.

2. In an apparatus of vthe'character described, the combination of the supportingframework, a breast hinged thereto, and means for adjusting saidgreast bodily in a vertical line with respecta-"tb th'e framework.

3. In-an a paratus ofrithe -character `described, a ginreast, a hinge one leaf or rnern-l ber of which is attached to saidbreast, and means connected with the other member of saii hinge for adjusting said member vertica y.

4. In an ap aratus ofithe character described a xe plate or support provided with ears or lugs, an adjustingfscrew mounted in said ears, and a' gin-breast provided with a hinge, one leaf of which is provided with ears or lugs in threaded engagement with said screw.

5. In an ap aratus ofthe character described a fixed plate or support provided with lugs or ears, a ginfbreast rovided with a hinge, one member of Wln'c is also prosee,43s

p vided with ears or lugs, and an adjusting device mounted in said first-named ears and connected with said .last-named ears to raise and lower the hinge and breast.

6. In an apparatus of the character de scribed a fixed plate or support provided with ears or lugs, a threaded adjusting spindie or screw having bearings in said lugs, a breast provided with a hinge, one lea't or member of which is formed v'ith lugs or ears interiorly threaded and engaging the threads of said screw, whereby by turning the latter the breast maybe raised or low ered and a 'locking-cap designed to hold said screw from turning.

7. In an apparatus of the character described, a iXed plate, a gin-breast provided with a hinge embodying two members pivotally connected together, one of said inembers being iixedly secured tothe breast, and

vvertically-adjlistable means connecting the other member of said hinge to said plate.

8.Y In an apparatus of the character described, a fixed plate or` support provided with lugs, a gin-breast providerl with a hinge one member of which is also provided with lugs, and an adjusting-screw mounted in said first-named lug and having a screw-threaded connection'with said last-named clng to raise and lower the hinge and breast, said screw having a polygonal head, and a locking-cap adapted to rit said head and provided with a downwardly-extending flange adapted to engage some stationary partv whereby to hold the screw from turning.

In ,testimony whereof I afiix my signature4 in presence of two witnesses. f
